to provide a sanitary cuspidor the contents of which can be removed as soon as deposited therein and the upper surface and vinterior of the. cuspidor instantly and thoroughly cleansed, so as to prevent the spread of disease therefrom. I accomplish this object by attaching to a cuspidor having a funnel-shape cover With an aperture therein inlet and outlet pipes for the flow of water and a conical ring placed above the funnel and concentric thereto and the function of which is to deflect sharply upon the face of the funnel jets of water whichissue fromV the perforations of a circular pipe placed within the cuspidor and connected with the inlet-pipe. The perforated circular pipe is situated at the upper portion of the cuspidor and occupies the space between the sides of the cuspidor and the funnel-shape top, which is provided with slots opposite the holes in the circular pipe. The circular pipe being thus situated is protected from expectoration and is therefore not clogged by filth, and the conical ring causes the jets of water to spread all over the surface of the funnel, upon which it deflects them.

My invention is illustrated by the accompanying drawings, in which- Figure lis a view of the top of said cuspidor.

Fig. 3 shows the situation of the cuspidor with reference to the exterior piping and conneet-ions.

Fig. l shows the rim of a cuspidor A, provided with a funnel-shape top B, having a central aperture, the rimwof the cuspidor having a conical ring C attached thereto and extending over a portion of the funnel B. The funnel B is pierced by slots D at its upper portion and beneath the conical ring C, said slots being indicated in the, drawings by dotted lines. Adjacent to said slots are the perforations in the circular pipe E, which is situated within the cuspidor A and immediately beneath its upper rim. The ring C and the funnel B are shown cut away to exhibit the circular pipe E and the outlet-pipe F.

Fig. 2 shows the cuspidor A in cross-section and having a'funnel-shape top B, which is preferably removable to afford easy access to the interior of thecuspidor. Attached to the rim of the cuspidor A and above the funnel B is a conical ring C, situated at a slight distance therefrom, and the surfaces of the ring and funnel being substantially parallel or at any angle to properly deflect the water.

The cuspidor A is provided with an inletpipe Gr, extending. to the top of the cuspidor and connected'with a circular pipe E, situated in the same plane as the slots D, (indicated by dotted lines in the drawings,) and pierced through the funnel B beneath the ring C.v The perforations in the pipe E are opposite to and in line with the slots D.

The water enters the pipe Gr and is conveyed to the pipe E, through the perforations of which it spurts through the slots D, striking against the inclined surface of the conical ring C and being deflected upon the surface of the funnel B, through the aperture in the center of which it reaches the interior of the cuspidor A, whence it escapes through the outlet-pipe F, the Orifice of which is raised above the bottom of the cuspidor, so that some water may always remain therein.

Fig. 3 shows the cuspidor A placed upon a floor H, the inlet-pipe G being' connected to the water-pipe land the outletpipe F fitting within the Waste-pipe J or connected therewith in any manner permitting the easy disconnection of the cuspidor.

If the flow of a continuous stream of water through the cuspidor is not desired, the pipe I may be closed by a valve K, which may be opened by pressure upon a knob L upon the end of a rod M, attached to said valve.

That l claim as my invention isl. The combination with a cuspidorhaving a slotted, funnel-shape top, of an inlet-pipe; a circular, perforated pipe within said cuspidor and connected with said inletpipe; per- IOO forations in said circular pipe adjacent to the slots in said funnehshape top; a conical ring above said funuebshape top and concentric thereto; and an outlet-pipe, substanially as 5 described.

2. Acuspidor having,r an inlet-pipe, a valve normally closing said pipe and provided with a rod, pressure u pon which opens said valve;

a circular, perforated pipe Within said cuspi- Io dor and connected with the inlet-pipeg a fm1- nel-shape `top concentric to the circular pipe and having slots in the same plane wit-l1 the perforatons in the circular pipe; a conical rinf,r above said funnehshape top and concenluric thereto; and an outlet-pipe, substantiall y 15 as described.
